I built DataFast to track revenue from traffic

483 days ago, I built my own web analytics out of frustration. I was using Plausible and loved its simplicity, but I felt stuck. Pageviews are nice, but they don’t tell you what makes money. So I built my dream tool: connect Stripe to traffic, and see where revenue actually comes from, so I can double down. Almost nobody cared. It took 120 days to reach $1k MRR. But I didn't mind. I was having fun. I shipped 117,869 lines of code to build features I needed myself. My only KPI was (and still is) features shipped. Slowly, word of mouth kicked in, and the SaaS started growing on its own. 16 months later: - $17K MRR - 983 paying customers - 1.2B pageviews tracked I wanted to quit many times. I’m competing with giants and VC-backed startups, in an overcrowded market, for a vitamin product. What changed everything was niching down: building ultra-specific features for my own problems and hoping others had the same ones. I don’t really do marketing. Most users come from word of mouth. But today is special. I never truly launched @DataFast_, so I made this video to finally do it. Hope you like it!

    And a massive thanks to all the early users who kindly sent feedback and helped me build a better product. Thank you, I could have done it without you 🙏

    This video wouldn't exist if I hadn't been tremendously inspired by the TLDV team. They created two masterpiece launch videos, and their Instagram account is a gem. youtube.com/watch?v=igSn0b…
